我国数字孪生城市发展初探

Research on the development of digital twin cities

数字孪生城市作为数字经济发展的重要载体,是未来城市形态演变的重要方向。我国数字孪生城市发展态势良好,但面临现实问题与各种挑战日益突出。本文系统梳理数字孪生城市概念及内涵,充分挖掘数字孪生城市核心技术特征,阐明物联感知操控能力、全要素数字化表达能力、三维可视化呈现能力、数据融合供给能力、空间分析计算能力、模拟仿真推演能力、虚实融合互动能力、自学习自优化能力和众创扩展能力,并对未来数字孪生城市的应用场景进行了展望,为推进数字孪生城市高质量发展提供参考依据。

As a crucial driver of the digital economy,the concept of a digital twin city represents an important direction for future urban development.While the growth trajectory of these cities is promising,they also face increasingly complex challenges and practical obstacles.This paper systematically clarified the concept and connotation of digital twin cities,thoroughly explored the core technical characteristics of digital twin cities,and demonstrates their abilities in perception and control of IoT,all-factor digital expression,three-dimensional visualization,data fusion supply,spatial analysis and calculation,simulation and emulation as well as virtual-real integration.The potential application scenarios of digital twin cities in the future were also anticipated to serve as a valuable reference for advancing the development of high-quality digital twin cities.
